Quest Exp Cheat
Locate quests.xml in the Main Game Folder right click and select Edit, where "XP" is found edit the number value to the right of it with the desired amount, however keep it within reason or you wont gain everything that goes with the level ups. 500-1000XP for each quest should suffice until you get further into the game and into higher levels. But you should experiment and see what value is best. Another good thing to note is each Quest in the lines has a Quest # and gives clues as to what quest it effects so you will know which one to edit for the Quest you are currently on.
As always ALWAYS backup any files you edit.
